A medical billing company's cold email should offer a review of the practice's own numbers, summary totals from an aging report or counts of rejected claims by payer and reason code, and should never contain, or ask for, anything that identifies a patient. Five complete emails are below, along with the rules that matter for this buyer.
The made-up sender is Dev Malhotra, owner of ClearLedger Billing, a 14-person billing company in Phoenix that works with independent physician groups and therapy practices. The company, the practices and the addresses are fictional.
The one rule for this industry
Your buyer works with protected health information every day and will notice anyone who handles it casually. In a first email, never include a patient's name, an account number or an example claim from a real client, and never ask the reader to send patient details by email. Ask instead for numbers with the identifying fields removed: counts of claims by payer, dollar totals by age bucket, and denial reason codes. Do not ask for claim-level rows with only the names cut out: under the HIPAA de-identification guidance from the Department of Health and Human Services, dates of service and other fields can still identify a patient, so a row-by-row export is still patient information. If the reply includes patient details anyway, tell the sender to stop and do not forward it. Practices will ask about HIPAA agreements before they share anything real, so have that paperwork ready for the call.
Who to write to
The Bureau of Labor Statistics says medical and health services managers plan, direct and coordinate the business activities of healthcare providers, including running a medical practice for a group of physicians, and that one of their duties is to manage finances, including patient fees and billing. It counted about 640,400 of them in 2025, with a median wage of $123,860 (May 2025), and offices of physicians employ 13 percent. In a three-doctor practice the person is often a practice administrator or office manager; in a larger group it may be a revenue cycle director. Write to that role, not to the physician, unless the physician is also the owner who handles the money.
Email 1: the claims review offer
Subject: Rejected claims at Desert Bloom Family Medicine
Hi Teresa,
I'm Dev with ClearLedger Billing in Phoenix. We work with independent practices on the claims that come back rejected or denied.
If you can pull a summary of the last 90 days of rejected claims, just the count and dollar total by payer and by denial reason code, I'll send you a one-page read on which ones look fixable. Totals only, please, with no patient rows. No charge.
Dev Malhotra, ClearLedger Billing, 4300 N Central Ave, Phoenix AZ 85012. Reply "stop" and I will not write again.
Why it works: it asks for numbers, not patient details, so a careful administrator will not be put off, and it promises a short document with a clear form. The request to leave patient information out also tells her you know the field.
Email 2: the open billing job post
Subject: The billing specialist opening at Camelback Physical Therapy
Hi Marcus,
I saw Camelback Physical Therapy is hiring a billing specialist. Practices that lose a biller often fall behind on claims in the weeks before the new person is trained, and that is when money ages.
I'm Dev at ClearLedger Billing. We can cover claim submission and follow-up while you hire, or take it over permanently if you'd rather not manage it. Would a 15-minute call be useful?
Dev Malhotra, 4300 N Central Ave, Phoenix AZ 85012. If you do not want these, reply "stop."
Why it works: the job post is public, and the offer solves the gap it reveals. Do not say you can fix the practice's denials before you have seen the data.
Email 3: a specialty practice
Subject: Billing for Scottsdale Dermatology
Hi Nina,
Dermatology billing has its own headaches: procedure codes that change with the visit, prior authorizations for some treatments, and cosmetic services that need to be kept apart from covered ones. I'm Dev at ClearLedger, and billing specialty practices is most of what we do.
If you tell me which payer gives you the most trouble, I'll tell you what I'd check first. A reply is all I need.
Dev Malhotra, 4300 N Central Ave, Phoenix AZ 85012. Reply "stop" to be removed.
Why it works: the question is small and specific. Use the specialty only if you really bill for it, and keep the claims about the specialty general enough to be true across practices.
Email 4: the follow-up that adds a checklist
Subject: Re: Rejected claims at Desert Bloom Family Medicine
Teresa, in case a 90-day summary is a lot to ask, here is a lighter version: just the top five denial reason codes from last month and how many claims each affected. That alone is enough for me to say whether outside help would make a difference. Dev
Why it works: it shrinks the ask to something an administrator can do in five minutes. Send it a week after Email 1.
Email 5: the reply to "we do it in house"
Subject: Re: Re: Billing for Scottsdale Dermatology
Nina, that is common, and a good in-house biller is hard to replace. Some practices use us for the claims that keep coming back, or as a backup when someone is out. If either would help, I'm glad to talk. Otherwise I'll leave you in peace. Dev
Why it works: it takes the objection seriously and offers two narrow, real uses.
Subject lines
Use the practice name and the concrete subject: "Rejected claims at Desert Bloom Family Medicine," "The billing specialist opening at Camelback Physical Therapy," "Billing for Scottsdale Dermatology." Avoid "Increase your revenue," "Maximize collections" and any promise of a percentage. Subject lines that promise money read as vendor mail and get filtered by staff. The longer list is in cold email subject lines that get opened.
Volume
Google's Workspace limits page says unique recipients per day are capped at 3,000 total, or 2,000 external, a limit nobody doing this properly will approach. A billing company writing to 100 practices should send 15 to 20 emails a day from one inbox. With a five-email sequence, that supports roughly 3 to 4 new practices a day. Practice administrators change jobs, so verify each address before sending. Cold email bounce rate explains what to do when messages bounce.
What the law requires of your email
The FTC's CAN-SPAM compliance guide says the law makes no exception for business-to-business email. Each message needs honest header information, a non-deceptive subject line, your valid physical postal address and a way to opt out, and you must honor an opt-out within 10 business days. Each separate email in violation can bring penalties of up to $53,088, according to the FTC. HIPAA is a separate matter between you and the practice once they become a client, and you should have your own counsel confirm those documents.
Personalize with the practice's public pages
Use the practice name, the specialty, the number of providers on the staff page, a posted billing job, and the payers the practice lists as accepted. Do not guess at the practice's revenue or at its denial rate. If a fact is not on the site, leave it out.
